I INVENTOH ALBERT lbw/mo EMowsa/V AT TOBNEY rm: COLUMBIA PLANMRAIII 50-. WASHINGTON, D c.

ALBERT EDWARD EDMONDSON, OF OTTAWA, ONTARIO, CANADA.

SAW.

Specification of Letters Patent.

Patented Aug. 26, 1919.

Application filed February 24, 1919. Serial No. 279,018.

To all whom it may concern Be it known that I, ALBERT EDWARD ED- MONDSON, residing at Ottawa, in the county of Carleton and Province of Ontario, Dominion of Canada, have invented certain new and useful Improvements in Saws, of which the following is a specification.

This invention relates to improvements in saws, and the object of the invention is to provide a saw having certain notches which when placed on a board will indicate a right angle in relation to the back of a saw.

With this and other objects in View, the invention consists in the construction, combination and arrangement of parts as will be hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claim hereunto appended.

In the drawings:

Figure 1 shows a perspective view of my invention in operative position, and

Fig. 2 shows a top plan view of same.

Referring to the drawings, like letters designate like parts in the various drawings.

A indicates a board or any other such like material which is desired to be squared. B is a saw having a straight back C and usual handle D.

The saw B is provided on its back O with a notch E near the handle D. F is an imaginary line drawn across the face of the saw B from the notch E and at right angles to the back of the saw C. One side of the notch E is out along this line, while the other side may be any shape desired. Near the toothed side of saw B I provide a slot copies 0! thin patent may be obtained for five cents each, by addressing the G having one straight side on the imaginary line F.

With this construction the saw can be laid on the board, and by inserting one finger in slot G so as to bring the straight side of this slot tight to the straight side of the board and having the straight side of the notch E parallel to the straight side of the board, it will be seen that the back of the saw will be at right angles to the said straight side of the board, thus acting as a square for making a square end on the board.

The notch E and slot G may be punched out when the holes are being punched for the rivets which hold the handle thus eliminating any extra cost in manufacturing a saw with this additional feature.

A saw of this construction can be used right or left-handedly.

From the foregoing it is thought that the construction of my invention will be clearly understood, and therefore a more extended explanation has been omitted.

What I claim as new is,

A saw provided with the usual handle and having a straight back, a notch cut in said back near said handle, one side of said notch being straight and at right angles to the said back, a slot punched out of said saw near the toothed side of same, said slot having one straight side, and said side being in line with the straight side of said notch.

In testimony whereof I afiix my signature.

ALBERT EDWARD EDMONDSON.
